3. All user data will be deleted in the rollback. Use an SD card, computer, or Cloud storage to back up all important data before rolling back your phone, and make sure all backed up content is complete and effective.
4. Make sure your phone has more than 50% battery remaining.
5. If you encounter any issues, you can go to HiCare, Huawei Club, or call the official VIP helpline at 400-930-9300.
